Hp DV6000 Boot Loop after Reflow of GPU

Specs: Windows 7
Hey Guys,

I just reflowed my gpu on my hp dv6000 which are known to have bad gpus. So before I put it all back together I connected the Power Ribbon and It turns on for about 3 seconds, the fan spins, then it shuts off, pauses for 3 seconds, and does this continuously. I took a 15 second video of this http://www.youtube.com/watch?v=NCyZ...

I have a firends same computer, I swapped out the ram and tried to put in one stick at a time and every combination, so I figure thats not the problem.

In order to test it I just plugged in the power ribbon, ram, HD, Disk Drive, Am I missing something?

Thanks a bunch for any suggestions!

At a guess you've probably overstressed some component by applying too much heat. You probably need to get a repair shop, with the appropriate test equipment, to have a look at it.

Did the GPU function prior to your solder job? If not, you can't be sure that you had identified the problem.

The GPU would work on and off, so I did a reflow as many people suggested, but I can't figure out why it would have the boot loop problem

Did you remove the CMOS battery before soldering? If not, try resetting the CMOS.

Not sure what you did with the CMOS battery. Once you took it out while there was no other power to the board, you must immediately enter the BIOS screens and reset the values there. At least the date and time will be wrong. Possibly other items.

Have you tried removing the CMOS battery while the AC adapter and the laptop battery are both removed. Before removing the CMOS battery, with the above removed, depress the power button a couple of times and then remove the CMOS battery and put it right back in. If still no go, I think your may have a bricked motherboard.

Contact HP tech support for any help they may be able to provide.
